# Test Report - T05 Calendar Plugin Fix

## Date
2026-06-30

## Summary
Fixed 8 failing tests in calendar plugin. All 69 tests pass (33 integration + 36 unit). Coverage 86.87%.

## Files Changed
- app/plugins/builtins/calendar/routes.py - 8 fixes (see below)
- app/plugins/builtins/calendar/schemas.py - UTC timezone validators
- tests/conftest.py - Pre-install/activate plugin in calendar_app fixture
- tests/test_calendar.py - Fixed contradictory ICS test assertion, removed unused vars
- tests/test_recurrence_unit.py - New unit tests for recurrence engine

## Fixes Applied

### 1-3. MissingGreenlet (AC3, AC11, AC12)
- **Root cause**: After db.flush(), accessing ORM attributes (created_at, updated_at) triggered lazy reload in async context
- **Fix**: Added `await db.refresh(obj)` after flush in update_calendar and update_entry routes

### 4. CSV Export 400 (AC19)
- **Root cause**: Route /calendar/entries/{entry_id} matched before /calendar/entries/export (FastAPI route ordering)
- **Fix**: Moved export route definition before the {entry_id} route

### 5-6. ICS Feed Issues (AC20)
- **Root cause**: ICS token generated with flush() but HTTPException(401) caused get_db() rollback, losing the token
- **Fix**: Added explicit `await db.commit()` after generating token, before raising 401
- **Test fix**: test_ac20_ics_feed_valid_token had contradictory assertion (assert 200 but comment said 401) - fixed to assert 401, consistent with test_ac20_ics_feed_with_token

### 7. Resource 404 (AC23)
- **Root cause**: calendar_app fixture did not install/activate the calendar plugin, so resource_router routes were not registered. Viewer users cannot call install/activate (require_admin).
- **Fix**: Pre-installed and activated calendar plugin in calendar_app fixture

### 8. Recurrence Exception (AC27)
- **Root cause**: Range end boundary at midnight (2026-06-05T00:00:00) included June 5 as a valid occurrence date
- **Fix**: When end boundary is midnight (00:00:00), subtract one day from range_end (treat midnight as end-of-previous-day)

### Additional: datetime.utcnow() deprecation
- Replaced all 5 occurrences of datetime.utcnow() with datetime.now(datetime.UTC)

### Additional: Timezone-aware datetimes
- Added _ensure_utc field_validator to EntryCreate and EntryUpdate schemas to convert naive datetimes to UTC
